The values of the magnitude of the impact and the value of its importance have been pre-established in reference tables. The sign, magnitude and importance of the impact When an interaction between an environmental factor and an action is relevant, a diagonal is drawn in that cell. Therefore, the potential impacts or interactions to be evaluated are 8,800.ĭepending on the evaluated project, the researcher selects the environmental factors and actions that he considers and can add some specific ones. The main disadvantage is the subjective burden on the researcher's decisions when assigning orders of magnitude and importance.Ĭalculation of the impact value in the Leopold matrix Actions, factors and their interactionįor Leopold's matrix, 88 environmental factors or components and 100 possible actions to consider are suggested. This matrix method of evaluation was proposed in 1971 by Luna Leopold in collaboration with other North American researchers.Īmong its main advantages are being a simple method to implement, low cost and applicable to all types of projects. The Leopold matrix is widely used as a qualitative evaluation method and allows to assign a character to the impact (positive or negative). This matrix systematizes the relationship between the actions to be implemented in the execution of a project and their possible effect on environmental factors. The leopold matrix It is a double entry table of cause-effect relationship used in the environmental impact assessment. Environmental impact assessment in construction.Environmental impact assessment (EIA) in wetlands and aquaculture.The sign, magnitude and importance of the impact.
